Filed: 1991-08-30
Abstract: PURPOSE:To easily remove the pulverized dirt sticking to the contact type charger without the inconvenience such as decreasing the charging quantity of the image carrier surface and generating the unsteady charge by holding again the contact type charger in contact with the charged area, and at the same time applying the voltage to the charger having the same polarity as the polarity of the surface potential of the charged area and being lower than the surface potential in the absolute value. CONSTITUTION:The pulverized dirt removal is performed at the timing of the timing chart. On receiving the printing command 1, the photoreceptor drum as an image carrier is made to start the rotation 2. Then, the drum is charged by applying 3 the voltage Vc=-1.1Kv to the contact charger. The developing bias Vb is changed 4 to -250V and the voltage of Vt=+6.5V is applied to the transfer charger too. Next, by changing the Ve and Vi shown as the steps 6, 8, 9 and 11, the negatively charged part A (Japanese square syllabary) is formed, to which the transfer charger has no action, and with which, after its single rotation, the contact charger applied with the 0V is brought into contact again. Thus, the dirt having the positive polarity on the charger is moved to the drum and removed.

Filed: 1988-10-03
Abstract: PURPOSE:To detect the premonitory sign of self-discharge from an ultraviolet ray detector, and to prevent danger by means of an adequate combustion control by judging that the intervals of electric discharge from the ultraviolet ray detector are within a preset value, and by producing an alarm signal. CONSTITUTION:When a shutter 4 is opened during a stationary burning operation, a fire detection signal is produced from a fire detection circuit 8, and a shutter drive circuit 6 is operated, thereby closing the shutter.

When the ultraviolet ray detector 2 deteriorates, the discharge pulse is generated even at the time of the closing of the shutter 4. The discharge pulse generated at the time of the closing of the shutter 4 is inputted into a microcomputer 14 via a comparing circuit 12 and a waveform shaping circuit 13, and the pulse intervals of the discharge pulse are counted by a timer counter to judge the output of an alarm signal.

Title: Manufacture of magnetic head
Inventor: TAKEURA TORU
IPC: G11B5/31
Filed: 1987-10-02
Abstract: PURPOSE:To easily manufacture without degrading the efficiency of a magnetic head by forming an insulation material forming a conversion gap on a conductor coil, removing the undesired part of the insulation material so as to expose at least the conductor coil. CONSTITUTION:The structure is adopted such that the conductor coil 4 is imbedded in the magnetic conversion gap, the conductor coil is formed on a magnetic base 1, an insulation member 3 forming the conversion gap is adhered over the entire face thereupon and the surface of insulation material is made flat so as to expose the conductor coil. Since the conductor coil is arranged up to nearly 1mum from a face of the magnetic head opposed to the magnetic head, the leakage of the generated magnetic head to an undesired part is avoided but the magnetic field acts effectively on the recording of the recording medium. Similarly at the time of reproduction, the magnetic flux detected from the medium is converted into a voltage in the nearby conductor coil. Thus, it is not required to form a slot having an apex angle zero to a ferrite base and a ferrite core chip 2 causing a large effect on the head efficiency to attain simplified structure.

Abstract: PURPOSE:To obtain a developing method having the most of advantages of both a two-component developing method and a one-component developing method, by forming a toner thin layer on the surface of a developer layer which is held magnetically on the outside peripheral surface of a non-magnetic cylindrical body. CONSTITUTION:A toner To which has been supplied onto a developing sleeve 4 being a non-magnetic cylindrical body is brought into contact with a carrier Ca and carried while improving the electrified potential, and passes through the opposed part to an electrification control member 9. In this case, since the negative polarity is applied to the member 9, the toner To which has been electrified to the positive polarity being opposite to said polarity is drawn out to the outside peripheral part, and a thin layer of a stable toner To is formed uniformly on the outside peripheral part. In this way, the toner thin layer which has been formed on the surface of the carrier Ca is brought into contact directly with an electrostatic latent image which is formed on the surface of a photosensitive drum 1 in a developing area X, and develops it. In this way, the purpose can be attained.
